Abstract: The tribo-mechanical evaluation of epoxy/periwinkle particulate composites was investigated. Periwinkle shell particles were used as reinforcement in the epoxy matrix. 3 to 9wt% periwinkle particles at intervals of 3wt% were added to the epoxy as reinforcement. Themicrostructural examination of the epoxy/periwinkle particulate composites was carried out using scanning electron microscope (SEM). The mechanical, physical and wear properties were carried out by standard methods equipment. The highest density was observed for the epoxy matrix at 1.76g/cm3 and the least for 9wt% composites at 1.52g/cm3, the highest water absorption was observed in the matrix at 1.5% and the least with 9wt% composites at 1.18%.The 9wt% composites had the highest hardness value at 76.4HV while the epoxy matrix had the least hardness at 39.8HV, the highest tensile result was observed in the 9wt% composite with a value 304 N/mm2 while the least value was observed with a value of 287 N/mm2 for the epoxy matrix. The microstructure of the composite is uniformly distributed and strong interfacial bonding occurred between the epoxy matrix and reinforcement; however agglomeration of particles were observed. The highest wear rate was observed in the epoxy matrix at 0.445mm3/m while the least wear rate was observed in 9wt% epoxy composite at 0.272 mm3/m.The development of the composite will contribute to knowledge helping to convert waste to wealth and reduce environmental pollution. The produced composites can be used in the production of plastic pipes for oil and gas industries.
